THOMASBAKER HUESTIS, OF BRISTOL, RHODE ISLAND, ASSIGNOR TO NATIONAL IN-DIA RUBBER COMPANY, F BRISTOL, RHODE ISLAND, A CORPORATION OF RHODEISLAND.

Application. filed November i particularly in the manufacture of rubberapp fabric and rubber footwear, it is neces;

of cement to one side sary to apply `a coat of the insole, applied to'alast with the cemented side out, the lower edges of the upper being thendrawn over the insole and secured, and the usual filler sole and otherparts being then lied. For many years it has been customary to cementthe insoles manually, this operation. requiring considerable time andlabor, and unless kthe operator is careful the coating applied is noteven and sufficient in quantity. More recently machines havebeen devisedfor accomplishing this result, but while more rapid than Athe handoperation they are open tonunierous objections. and are easily cloggedowing'to the viscous nature of the cement used thereby requiringconsiderable time and labor in cleaning.

An'object of my invention is to provide a simple, rapid, efficient andcompactmachine for applying coatings to sheet articles. Another objectis to provide an improved machine for applying cement to insoles forfootwear articles.

Still another object machine having an improved anism.

A further object is to provide a coating machine which can be readilydismounted for purposes of cleaning and repair and which will notreadily clog in operation.

A still further object is to provide a machine in which the finishedarticle is delivered in such position that the proper working of themachine may be readily determined.

r1`he invention consists broadly in cooperis to provide a coatingcoating mechating coating and feed rolls provided with means whereby aneven, relatively thick coating may be applied, a reservoir forthecoating material disposed to present the material to a relatively largearea ofv the coating. roll, a guide means for reversing the position ofthecoated article and returning it adjacent to its starting point in theina-A chine. l

For a detailed disclosure of the nature the insole after drying being pconcerne MACHINE.

Referring to the drawings, the numeral 1 designates the base of themachine which is supported by the legs 2. Extending upwardly from thebase 1 is a column 3 carrying at its upper enda table or support 4 uponwhich is mounted the drive mechanism. In the present instance the driveis from an electric motor 5, the shaft 6 of which is connected by areduction gear mechanism 7 to a shaft 8 on which is mounted a sprocket 9engaging the drive chain 10. This chain can be tightened by means of anidler sprocket 11 mounted'on an arm 12 pivoted to the shaft' 8 andadjust-ably secured in position at 18. It will be obvious that any otheri ,connected to the shaft 15 by means of the known form of clutch 18operable by the handle 19.- Disposed above the cementing roll 16 is acooperating idler or feed roll 20, the shaft 2l of which is mounted inthe arms of a yoke 22 pivotally connected to the frame at 23. Extendingupwardly from the yoke 22 is an arm 2-1 through the upper end of `whichloosely passes a rod 25 mounted on the frame 14. Surrounding the rod isa coiled spring 26 bearing at one end against 4 quent pressure of die:feed roll 20 against.

In addition suchsqueezing action would form a bank of cement at the point where theinsole first meets the rolls, and as the rear end of an insole passesthis point the bank of cement would be transferred to the feed roll 20with lconsequent marring .and depositof cement on the upper surface ofthe insole. As the insole issues from between the rolls with itslowerside cemented its end engages the guide 59, and as before stated itis thereby bent or deflected so that as it issues from the lower end ofthe guide 59 its direction is reversed and its cemented side isuppermost. As the insoles pass between the curved outer wall 60 ofthezreservoir and the guide 59 the cemented side of the insoles wouldtend to stick to the wall 60 but by the provision of the ridges 61 and.

the ridges 62 on the guide 59 the bearing of the insole on the walls ofthe passageway is reduced to a minimum. In the same way the curvedsupports 64 on the conveyor 63 prevent sticking of the insole to theconveyor.

It will'be seen that by the construction above described a very compact,simple and rapid machine has been devised. By reason of the return ofthe cemented articles ad\ jacent to the feeding point the operator isable to readily determine Whether the ma-l chine is operating properlyby an inspection of the articles, and he can do this at all timeswithout"interrupting the process of feeding soles to the machine. Byreason of the close. fitting of the cementrcs'ervoir 44 to the roll 16and the relatively deep immersion of the latter in the cement anadequate supply of cement is insured, vwhile at the same time theexposure of cement to the atmosphere is reduced to a minimum. Should theoperator desire to inspect or clean the reservoir 44 the latter can beinstantly dismounted and easily cleaned.

With the above detailed disclosure of the invention numerousmodifications will suggest themselves to those skilled in the art, andit is thereforenot desired to limit the invent-ion otherwise than as setforth in the appended claims.

Having thus described my invention what I claim and desire to protect byLetters Patent is: v
